Ecology and the environment
Studying populations in place
In ecology scientists are concerned with understanding what determines population size and how populations of different species interact within ecosystems. Pond ecology, for instance, could involve studying algae to understand how algal population growth affects water quality in ponds, and how that in turn affects the survival of fish and other animals.
Biodiversity, an important concept for ecologists, measures the diversity of life – usually the number of different species in a given area.Lead image:
